Yup, same here.

Now, look at rpc.mountd, the thing responsible for doing the mounts, aka
mountd.

ted@dondra:~$ ldd /usr/sbin/rpc.mountd
        libwrap.so.0 => /lib/libwrap.so.0 (0x40022000)

Yes, that's true.

For the archive, and those less well versed, "explicitly stated in
inetd.conf" would mean a line that contains "/usr/sbin/tcpd" in the
"server program" field of inetd.conf... in other words, it's either linked
against tcpwrappers libwrap, or you've specified tcpd as part of the
invocation command line.
